Distances are measured slope distance to face of the tree at DSH. All live conifer trees within the subdivision, including boundary trees, greater than or equal to minimum DBH in A.2 count towards residual stocking.
These specifications apply only to trees that meet the minimum tree diameter stated in A.2. For all trees that meet A.2 log removal specifications
All Subdivisions (1-25)
End Result: After treatment, these areas will have an average stand density 40 ft2 per acre of basal area (excluding ponderosa pine ≥ 21” DBH and 26” DSH) and increased variability in the structure and spatial arrangement of the residual trees in the form of individual trees, clumps, openings, and retention patches. The residual area will have an increase in its mean diameter, a reduction in ladder fuels, as well as a shift in composition and structure towards mature trees, larger trees, fire-adapted conifers, and other desirable species. A basal area factor of 10 will be used to determine stocking compliance.
